Abstract

Accumulation of arsenic has potential health risks through consumption of food. Here, we inserted the arsenite [As(III)] S -adenosylmethionine methyltransferase (ArsM) gene into the chromosome of Pseudomonas putida KT2440. Recombinant bacteria methylate inorganic arsenic into less toxic organoarsenicals. This has the potential for bioremediation of environmental arsenic and reducing arsenic contamination in food.
